MILTON S. OABELL, OF QUINOY, ILLINOIS, ASSIGNOR OF ONE-HALF TO WILLIAM SOHAEFER, OF SAME PLACE.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 289,888, dated December 11, 1883,

' Application nied october 5` 1883. (No modem To all whom may concern:

Be it known that I, MILTON S. GABELL, of Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this speciiication, and to the letters of reference marked thereon.

My present invention relates particularly to that class of oil-cups wherein the lubricant is fed by gravity or by the condensation of steam; and it consists in the combination and arrangement, hereinafter described, and pointed out in the claim, whereby the feeding and delivery of the lubricating material is regulated and controlled.

The structure of the device will readily be understood from the accompanying drawing, representing a sectional View of my improved lubricator.

Located within the oil cup or reservoir A is a hollow stem', B, passing through a stuiflngboX, K, in the top of the cup, and provided with a conical or other suitably-shaped eX- tremity adapted to fit and close the orifice D in the bottom of the cup. The hollow stem or spindle B is provided with avent, E, opening into the cup A near the top thereof, and vwith astufflngbox in its head, through which passes the spindle or stem C, whose extremity isv adapted to engage with the valve-seat M, located with the stem B, but below the vent E. A glass sight feed-tube is interposed between the neck F at the bottom ofthe cup A and the iitting I, for attachment to th e steam pipe, steam- -chest, or other part to be lubricated.

` oriceD, drop by drop or in a stream, as desired, by simply adjusting the hollow stem B, controlling the outlet D, or the stem O, controlling the vent, or by adjusting both of said valves, as the exigencies of the case render necessary or desirable. As the oil passes from the cup A in the form of drops or in a stream, it is visible through the glass tube G, thus enabling the operator to observe the Working of the apparatus and determine the proper adjustment of the valves. If desirable, a gage may be attached to the side of the cup A, to indicate the height of oil contained therein.

Although this lubricator is arranged and designed, primarily, as a gravity-feed, it may be readily converted into an overflow-feed by screwing the stem B tightly against its seat and allowing the steam to condense in the cup A, the displaced oil being delivered through the vent E and hollow stern B.

When intended for use as an overflow-feed, a cock may be attached at the lower end of the cup,to draw off the water of condensation; or the Water may be discharged from the `cup down through the orifice D and through the ports G I by raising the lower end of the spindle B from its seat, as will be readily understood.

The combination of the oil-cup A, having Witnesses:

WM. SGHAEFER, WM. ABEL.
